Is it safe for a D function (called from C++ code) to throw an exception, and have the stack unwind through the C++ call stack and caught by D code at the bottom of the stack?  Or will it potentially interact badly with the C++ part of the call stack?  I'm guessing C++ dtors may not get called, etc.?
